Corsair’s MP700 rivals the best SSDs around, and it’s also one of the few PCIe 5.0 SSDs in the retail market. However, consumers better heed Corsair’s listed requirements and put an M.2 heatsink or cooler on the MP700, as the drive can experience uncontrolled thermal shutdowns if pushed hard enough without one.

Phoronix and TechPowerUp have demonstrated what happens if consumers don’t adequately cool the Corsair MP700. Phoronix encountered malfunction issues in less than three minutes that caused the operating system to generate file system errors, implying that data corruption could result, while TechPowerUp saw thermal shutdowns in less than two minutes. We followed up with Phison, and the company issued the following statement to Tom’s Hardware:

“After carefully reviewing the recent reports from TechPowerUp and Phoronix, Phison would like to acknowledge the issue found in the reviews of products using the new Phison PS5026-E26 controller. We take this matter seriously and are committed to resolving it promptly.

Our firmware engineering teams have already isolated the problem and made the necessary adjustments to the thermal throttle curve within hours of the report. However, the new firmware must undergo Phison’s strict validation process before our partners can release it to customers. Rest assured our partners will notify end-users as soon as the validated update is available.

It is important to note that all E26 SSDs shipped without a heatsink are intended to be used with a heatsink. Most motherboards shipping with PCIe Gen5 enabled also include cooling specifically designed for Gen5 SSDs. We offer the “bare drive” option to allow customers to use their existing cooling products.

We want to emphasize our commitment to providing high-quality products and solutions to our customers and will continue to work diligently to ensure their satisfaction. Thank you for your patience and understanding during this process.” - Phison representative to Tom's Hardware.
